Researchers Detail AppSync Cross-Tenant Vulnerability in Amazon Web Services

Researchers Detail AppSync Cross-Tenant Vulnerability in Amazon Web Services

Nov 28, 2022
Amazon Web Services (AWS) has resolved a cross-tenant vulnerability in its platform that could be weaponized by an attacker to gain unauthorized access to resources. The issue relates to a  confused deputy problem , a type of privilege escalation where a program that doesn't have permission to perform an action can coerce a more-privileged entity to perform the action. The shortcoming was reported by Datadog to AWS on September 1, 2022, following which a patch was shipped on September 6. "This attack abuses the AppSync service to assume [identity and access management]  roles  in other AWS accounts, which allows an attacker to pivot into a victim organization and access resources in those accounts," Datadog researcher Nick Frichette  said  in a report published last week. In a coordinated disclosure, Amazon  said  that no customers were affected by the vulnerability and that no customer action is required. It described it as a "case-sensitivity parsing issue w
Unpatched Travis CI API Bug Exposes Thousands of Secret User Access Tokens

Unpatched Travis CI API Bug Exposes Thousands of Secret User Access Tokens

Jun 14, 2022
An unpatched security issue in the Travis CI API has left tens of thousands of developers' user tokens exposed to potential attacks, effectively allowing threat actors to breach cloud infrastructures, make unauthorized code changes, and initiate supply chain attacks. "More than 770 million logs of free tier users are available, from which you can easily extract tokens, secrets, and other credentials associated with popular cloud service providers such as GitHub, AWS, and Docker Hub," researchers from cloud security firm Aqua  said  in a Monday report. Travis CI is a  continuous integration  service used to build and test software projects hosted on cloud repository platforms such as GitHub and Bitbucket. The issue, previously reported in 2015 and  2019 , is rooted in the fact that the  API  permits access to historical logs in cleartext format, enabling a malicious party to even "fetch the logs that were previously unavailable via the API." The logs go all
Cross-Regional Disaster Recovery with Elasticsearch

Cross-Regional Disaster Recovery with Elasticsearch

Apr 13, 2022
Unsurprisingly, here at  Rewind , we've got a lot of data to protect (over 2 petabytes worth). One of the databases we use is called Elasticsearch (ES or Opensearch, as it is currently known in AWS). To put it simply, ES is a document database that facilitates lightning-fast search results. Speed is essential when customers are looking for a particular file or item that they need to restore using  Rewind . Every second of downtime counts, so our search results need to be fast, accurate, and reliable. Another consideration was disaster  recovery . As part of our  System and Organization Controls Level 2 (SOC2)  certification process, we needed to ensure we had a working disaster recovery plan to restore service in the unlikely event that the entire AWS region was down. "An entire AWS region?? That will never happen!" (Except for  when it did )  Anything is possible, things go wrong, and in order to meet our SOC2 requirements we needed to have a working solution.

Hackers Use Cloud Services to Distribute Nanocore, Netwire, and AsyncRAT Malware

Hackers Use Cloud Services to Distribute Nanocore, Netwire, and AsyncRAT Malware

Jan 12, 2022
Threat actors are actively incorporating public cloud services from Amazon and Microsoft into their malicious campaigns to deliver commodity remote access trojans (RATs) such as  Nanocore ,  Netwire , and  AsyncRAT  to siphon sensitive information from compromised systems. The spear-phishing attacks, which commenced in October 2021, have primarily targeted entities located in the U.S., Canada, Italy, and Singapore, researchers from Cisco Talos said in a report shared with The Hacker News. Using existing legitimate infrastructure to facilitate intrusions is increasingly becoming part of an attacker's playbook as it obviates the need to host their own servers, not to mention be used as a cloaking mechanism to evade detection by security solutions. In recent months, collaboration and communication tools like  Discord, Slack, and Telegram  have found a place in many an infection chain to  commandeer and exfiltrate data  from the victim machines. Viewed in that light, the abuse of
